' HINGE.

SPECIFICATIQN forming part of Letters Patent No. 308,883, dated December9, 1884.

Application filed December 8, 1883.

To aZZ whom it may concern.-

Be it known that I, W'ILLIAM M. DUOKER, a citizen of the United States,residing in the 'city of New York, in the county of New York and Stateof New York, have invented certain new and useful Improvements inHinges; and I do hereby declare the following to be a full, clear, andexact description of the invention, which will enable others skilled inthe art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, which form a part of thisspecification, and in which- Figure 1 is a view' of the back of a boxwith the cover attached by my hinge. Fig. 2 is a cut section of Fig. 1,showing the hinge inserted into the wood. Fig. 3 is a cut section of abox similar to F ig. 1, showing another method of applying my hinge.Fig. 4 is a side view of the hinge with the staples in place, andshowing one form of teeth. Fig.

. 5 is a top view of Fig. 4.. Fig. 6 is an end view of Fig. 4, and showsthe staple made with barbs. Fig. 7 is a side view of a hinge, showinganother form of teeth. 'Fig. 8 is an end view of oneof the teeth of Fig.7, showing the same barbed. Fig. 9 is a side view of a hinge adapted tobe secured by a screw. Fig. 10 is a top View of Fig. 9. Fig. 11 is anend view of Fig. 9. Fig. 12 is a portion of a piano -top, showing theswinging lid Z attached by the hinge Fig. 9.

Similar letters of reference indicate like parts in all the drawings.

In making my hinge, two blanks or arms, a a, which may be alike, are cutor stamped, preferably from a sheet of metal, to form a rectangularshape, having at one side or corner suitable projections to form theears I), through which they are united parallel-wise by the pintle c. Toattach this hinge to the box or structure all that is necessary is tomake a cut therein of the depth of the arms a a, and a small recess, toallow movement to the pintle, and then insert the hinge edgewise intothese cuts, as shown in Figs. '2 and 3.

I show a number of means to. secure the hinge in position after it isinserted in place. One is to out a notch or slot, d, on the upper edge,and drive a staple, 0, down to fit in this notch. For many uses theordinary double- (No model.)

pointed tack will be a sufficient holding device, especially when usedin connection with the teeth or projections hereinafter mentioned; orthe shanks of the tack or staple may be provided with barbs orcorrugations; as indicated in Fig. 6, or a larger or stronger staplewith or without barbs or corrugations may be employed, depending uponthe strength required in any particular application of the hinge. Theattachment of the arms is still further secured or strengthened byextending from their lower edge the teeth or pins f or f, which aredriven into the wood, and which may likewise have corrugations or barbs,as indicated in Fig. 8; or they may have swelled-out portions, as shownin Fig. 7, or have both the swelledout parts and the barbs, to secure afirm and rigid connection.

In that form of my hinge provided with the pins f f, having swelled-outparts, there is an enlargement of the pin between the arm a and thepoint of the pin. hen two such pins are used, the enlarged parts may betoward each other, as shown in Fig. 7 and when these are driven into thewood the effect is to 00111- press the wood between the pins f f whilethey are driven home, and then the wood expands into the enlarged spaceabove and be tween the swelled-out parts of those pins, thereby making avery firm and strong attachment.

Another method of securing the hinge, and the one which I consider thebest for use on piano-covers, is that shown in Figs. 9 to 12. In thisslits are made in the blanks or arms a a, and the parts 9 h '6 areforced out sidewise, leaving an opening for the stem of the screw, theupper edge being also rounded out to receive the head of the screw. Inthis method of securing the hinge the pins or teeth f may also beemployed in addition to the screw but I deem the screw sufficient. Thesearms a a are inserted in place in the.sa1ne man ner as those alreadydescribed; but in addition to the cut a suitable opening should beprovided to receive the swelled-out parts 9 h a, through which the screwpasses to se cure the arms in place. These hinges are adapted to be usedespecially on pianos or other structures where hinges are desirablewhich do not expose much metal surface to view; and they may be drivendown below the adjoining surfaces and readily covered over, to be stillmore concealed; but they may also be used for any purpose where a simpleand strong hinge is required.

This construction of hinge has many advantages over hinges heretoforeknown. It requires very little metal or work to make it, and it can beeasily attached. The arms can be made as long as the width of thematerial of the box or structure, so that in a box of half-inch stuffeach arm can be half an inch long and extend clear across the material,thus giving a brace against lateral motion of the full strength of thematerial. The holding device employed gives a firm and rigid attachment,and when the teeth or pins are used the cut in the stuff acts as a guidefor driving them into the proper place. It possesses the full strengthof a mortise-hinge containing an equal amount of material, and requiresa great deal less labor and skill to attach it. It is as cheap as orcheaper than the ordinary leaf-hinge, and attached about as easily assuch a hinge.

These hinges can be stamped or cut out from sheet metal. They areexceedingly simple and cheap in construction, very strong and firm inholdingpower, and can be easily applied.

I am aware of Letters Patent Nos. 181,843 and 238,320, describing hingesprovided with shanks or teeth, and hinge-connections bent at rightangles thereto, and to be attached without screws or nails.

I am aware of the patent to H. E. Griffin, dated December 10, 1878, andbearing No. 210,686 5 but I do not claim any of the matter therein shownand described.

What I do claim is- 1. In a hinge, the arms a and pintle 0, uniting thesame at right angles to their plane of movement, in combination with astaple, e, for securing said arms to their respective hinged parts.

2. In a hinge, the arms a, acting in parallel planes, and having ears 0,notches d, for the purpose described, and drive-spurs, in combinationwith the staple e, for securing said arms to their respective hingedparts.

3. In a hinge, the arms a, carrying drivespurs, said spurs having anenlargement midway of their length, for the purpose set forth.
